 * $wgBlockTargetMigrationStage, which was introduced in 1.42, is now deprecated
   and has no effect.
+* (T382987) The default value of 'http.dnsbl.sorbs.net.' in $wgDnsBlacklistUrls
+  has been removed. This is because sorbs.net have stopped providing their
+  services. This means that if you have $wgEnableDnsBlacklist set to true, it
+  will no longer provide any value unless you add other servers to
+  $wgDnsBlacklistUrls.
